There is no evidence that Ebola survivors have immunity to the coronavirus – who

At the moment there is no convincing evidence that patients who recover from COVID-19, stable developed immunity to re-infection by the coronavirus SARS-CoV-2. This is stated in the statement of the world health organization, published on April 24.

“Some governments suggested that the detection of antibodies to SARS-CoV-2 can serve as the basis for the issuance of “immunity passport” or “certificate of risk” that would allow people to travel or to return to work because they are protected from re-infection. Currently, there is no evidence that people who have recovered from COVID-19 antibodies and are protected from re-infection,” – said the who.

The organization notes that people who recovered from infection, do have antibodies to the virus, but “some of the survivors have very low levels of neutralizing antibodies in the blood.” In addition, at the moment has not been a single specialized research about how does the presence of antibodies to SARS-CoV-2 sustained immunity.

The who indicates the inaccuracy of tests that detect antibodies to SARS-CoV 2: they can give false negative results and false positive (so people without a history of COVID-19, can be mistakenly identified as having immunity). In addition, stresses the who, the rapid tests must distinguish SARS-CoV-2 from other coronaviruses. “Four types of human coronaviruses cause colds and widespread. The other two is the virus that causes middle East respiratory syndrome [MERS] and acute respiratory syndrome [SARS],” – reminded in the organization.

Who said that testing for the presence of antibodies to the coronavirus SARS-CoV-2 “is crucial for understanding the extent and risk factors associated with infection”, but these studies are “not designed to determine whether the recovered are immune to re-infections”.

Flash coronavirus infection COVID-19 began in December 2019 in the Chinese city of Wuhan. March 11, 2020, the world health organization declared the spread of the coronavirus pandemic. According to data from the American Johns Hopkins University, coronavirus in the world were infected more than 2.73 million people, more than 191,9 thousand of them died, 750,9 thousand recovered.
